Advanced Policies: Sending HTTP Service Callouts to Applications

195

add responder policy 'http.req.url.eq("/callout.pl").NOT && sys. http_callout(MyCalloutPL)' some_action

Also, if you modify an expression in an HTTP callout policy, you may get an error if any policy that invokes it is bound to a new policy label or bind point. For example, suppose that you create an HTTP callout policy named myCalloutPolicy1, and invoke it from a rewrite policy named rewriteCalloutPolicy1. If you change the expression in myCalloutPolicy1, you might receive an error when binding rewriteCalloutPolicy1 to a new bind point. The work-around is to modify these expressions before using the callout in the policy.
